Determine if point is within bounding box

Question

How would you determine if a given point is within the bounding box?

My point is 48.847172 , 2.386597.

Boundingbox:

    \"48.7998602295\",
           


        

Answer 1

This solution also takes in consideration a case in which the UI sends a box which crosses longitude 180/-180 (maps views on low zoom level where you can see the whole world, allow infinite cyclic horizontal scrolling, so it is possible for example that a box's bottomLeft.lng=170 while topRight.lng=-170(=190) and by that including a range of 20 degrees.

def inBoundingBox(bl/*bottom left*/: Coordinates, tr/*top right*/: Coordinates, p: Coordinates): Boolean = {
    // in case longitude 180 is inside the box
    val isLongInRange =
      if (tr.long < bl.long) {
        p.long >= bl.long || p.long <= tr.long
      } else
        p.long >= bl.long && p.long <= tr.long

    p.lat >= bl.lat  &&  p.lat <= tr.lat  &&  isLongInRange
}
